Question about 2003 Pontiac Sunfire
Also fog lights inop???
Well, don't guess at it like that, get a readout of the trouble code stored in the car's ECU. Any auto mech can do this for you, and in the USA Autozone as well.
You will find a code like P0135 or some such, and this will have a meaning specific to your car, so you can home in on the fault.

My 2002 pontiac has the exact same problem. I took it to my trustworthy mechanic and he told me that there is three Oxygen sensors in the emissons system. This light came on when one of them went bad. He said it is no big deal to have one go out, however if the second one goes out the car will start missing and running rough. Keep an eye on the performance of your car and if it does not dimenish then you should be alright. Fyi the oxygen sensor costs about $80 plus labor to replace it.
